Both of them.
A always has the same as T G always has the same as C Adenine, Thyamine, Guanine and Cytocine
A DNA molecule may have the same percentage of guanine and cytosine because they bond together through three hydrogen bonds, forming a stable base pair. This complementary pairing ensures that the total percentage of guanine always equals the total percentage of cytosine in a DNA molecule, known as Chargaff's rule.
Using more regions of the genome increases the complexity of the DNA fingerprint, making it less likely for two people to have the same combination of alleles at all the regions. This decreases the probability of finding two identical DNA fingerprints in a population.
Identical twins are formed by the human egg splitting after being fertilized. The DNA also splits, and each new egg contains the DNA of the original. This means that the twins, once born, have identical DNA. It's worth nothing that they won't have the same physical fingerprint.
They should be identical to the original DNA that underwent replication.

Two such people would be 'identical twins' . In every other case DNA is unique to each person.
Replication is an exact process without it we would all have incredible mutations.
It is very unlikely that two brothers would have babies with the same DNA. That could only happen if identical twin brothers married identical twin sisters, and even then the mixing of DNA during reproduction makes this an extremely unlikely outcome.
The question itself is not clear. Two cells that have just divided will have the MOST similar DNA. If we are talking about whole organisms or individuals, then clones would have the most similar DNA, similarly identical twins would have near identical DNA. Siblings have very similar DNA but not identical of course.
that no two people have the exact same DNA
It is very unlikely for two people to have the exact same DNA, except in the case of identical twins who share nearly identical genetic material. Even siblings from the same parents have unique combinations of DNA due to the random assortment of genetic material during reproduction.

DNA percentage is used to determine genetic relationships between individuals by comparing the amount of shared DNA. The higher the percentage of shared DNA between two individuals, the closer their genetic relationship is likely to be. This can help determine how closely related individuals are, such as siblings or cousins.
